Title: Printer print system
Inventor: NAKA TOSHIAKI
IPC: G06K15/10
Filed: 1978-12-26
Abstract: PURPOSE: To control print intervals in proportion to the counted number of clock pulses, equivalent to the pulse width of a timing signal, generated by a separately- provided clock, by extracting the timing signal from the rotational frequency of a recording-form feed motor in a line-dot type thermal printer.  
     CONSTITUTION: On indication of the start of printing, recording-form driving motor 4 starts turning and printer driver 9 waits for indication from down-counter 8. As a result, timing generating circuit 5 generates a pulse. Up-counter 7 counts its pulse width by a 1st clock pulse generated by clock-signal generating circuit 6. Its count value is transferred to counter 8 and at the end of transfer, counter 8 counts down the preset number of counting tuning to a 2nd clock pulse generated by circuit 6. Simultaneously, down-counter 8 sends a signal to printer driver 9 and transmits print pulses to thermal head 10.

Title: Word length varying circuit of storage circuit
Inventor: KASAHARA TOSHIROU
IPC: G06F7/00
Filed: 1982-09-16
Abstract: PURPOSE:To utilize effectively a storage area even when word length varies by shifting every (n)-bit address data toward the low-order digits and assigning the same address to plural storage circuits. CONSTITUTION:When a word-length switching signal outputted from a control circuit 1 is false, an address shifting circuit 27 outputs the address data 4 as address data 26 as it is. Therefore, the allocation in an address space is as shown in a figure (A). In this case, data A-D are 8-bit data. When they are converted into 16-bit constitution, a signal 18 is made true. Consequently, data obtained by the circuit 27 through an address bus 4 is shifted, bit by bit, toward the low-order digits. Further, 0 is outputted as the most significant digit address signal among data 26. Thus, the same address is assigned to storage circuits 5 and 6, and the data is stored with the word length of the 16-bit constitution as shown in a figure (B) while the stored 8-bit data are allocated equally.

Title: Recorder for digital video signal
Inventor: SUDA MOTOHARU
IPC: G11B20/18
Filed: 1986-07-08
Abstract: PURPOSE:To omit a memory needed for rearrangement of data by controlling a write address to rearrange the data when data are written in a memory for conversion of a product code into a series C2 from a series C1. CONSTITUTION:An even-odd separating circuit 2 separates the input digital video signals into an even series consisting of even words and an odd series consisting of odd words. These even and odd series are written to memories 5 and 6 respectively. When the odd series is written in the memory 6, the recording positions of words which are adjacent to each other in terms of time and included in both even and odd series are shifted from each other in the lengthwise direction of a magnetic tape. Thus a memory exclusive for rearrangement of data is omitted and therefore the constitution of a video signal recorder.
